#Revolutionary tidal fence is set to trap the sea power A British company has announced plans for an array of unique marine turbines that can operate in shallower and slower-moving water than current designs.

And just to visualise that, it like one small nuclear reactor worth of electricity being generated from the tides in the Bristol Channel. he new Transverse Horizontal Axis Water turbine (THAWT)
and should be suitable for the waters around Britain, as well as overseas. Because the turbines sit horizontally beneath the surface of the sea
they can be sited in water shallower than the 30-metre depth typically required by current designs.
And because the water is slow-moving, the company says, fish can safely avoid the turbinesblades.
Although the technology is regarded as environmentally benign, Kepler says it will still undergo a rigorous environmental impact assessment during the planning process to ensure that it poses no significant risk to marine life and to other users of the sea.
There is more good news for proponents of renewable energy after the UK government #which is no longer encouraging onshore wind

'The National Science Foundation-funded project is a collaboration between Shen University of Maryland atmospheric scientist Phillip A. Arkin and National oceanic and atmospheric administration climatologist Thomas M. Smith.
About eighty-four percent of all rain falls in the middle of the ocean with no one to record it.
New tool for climate change modelsfor example Shen referenced a region in the middle of the Pacific ocean that sometimes glows bright red on the computer model indicating extreme dryness

Kuosmanen's dynamic model enables the analysis of the development of nutrient stock over time and the distribution of the nutrient flows into water air and soil.
It accumulates in an underground cave system and flows into the ocean unused. For several years now KIT scientists in cooperation with German industry partners have developed simple technologies to extract
and distribute this water under the Integrated Water Resources Management (IWRM) project. They also implemented solutions for water processing quality assurance and sewage treatment.
The new technologies and concepts serve as models for other karst regions. Under the IWRM Indonesia joint project funded by the Federal Ministry of Education
For the first time they succeeded in completely filling a karst cave with water. In 2010 they handed the cave power station over to the Indonesian authorities.
The plant can supply 80000 people with water. For the water to reach the households in a clean state via the distribution network a team headed by microbiologist Ursula Obst who directs the partial project for water processing and water quality assurance developed methods for the central semi
-centralized and local processing of water. The water from the cave is filtered first with sand
in order to prevent turbid substances from entering the distribution network. In the next step bacteria in the tap water are reduced.
For this purpose the KIT scientists established a pilot plant at the hospital of Wonosari There bacteria in the water are reduced among others by UV radiation
and the addition of chlorine or by filtration using ceramic membranes. However these methods require high-voltage current
There animals and plants can pollute the water. We therefore recommend to cover the pool
The scientists also installed a sand filter that retains dirt and turbid substances when tapping the water.
Prior to use the inhabitants filter the water again with the help of a clay pot that is provided with very small holes.
The water released via these holes is potable. The pots are produced by Indonesian potters using local materials according to specifications made by the scientists.
For water quality control the scientists apply a rather simple method: Users take a small water sample
and mix it with an enzyme substrate a nutrient that activates certain enterobacteria Only if these enterobacteria are contained in the water they convert the substrate
and a clearly visible yellow color develops. If the water is contaminated the cleaning steps are checked
and the filtration system is repaired if necessary. A sewage system is still lacking in the region of Gunung Kidul.
In case of strong rainfall there is a high risk of the germs entering the groundwater especially in a karst region Fuchs says.

#Saturas Successfully Conducts Field trials of Embedded Stem Water Sensor The field tests were conducted on peach and citrus trees at the Hula Valley Orchards Experimental Farm.
The results were consistent with the stem water potential measurement using manual measurement tools and successfully demonstrated continuous measurement of the water status in the tree.
Based on the research of Dr. Moshe Meron Saturas has developed a miniature stem water potential (SWP) sensor that is embedded in the trunks of trees vines and plants.
SWP is recognized a scientifically highly accurate parameter for determining water status in crops but today SWP can only be measured in a labor-intensive procedure.
The Saturas sensor provides accurate information for optimized irrigation to reduce water consumption with no stress to the plants and increases fruit production and quality.
The Saturas sensing system tailors irrigation to the crop's real-time water needs resulting in more efficient water use
